Introduction
The PT8A976, PT8A976A and PT8A976B are CMOS LST designed for the remote controlled toy. The received signal is amplified by the three-stage amplifier, and then the appropriate amplified signal is sampled, fault-tolerantly checked and decoded to control the actions of the remote-controlled toy.There is an oscillator in all of the PT8A976 , PT8A976A and PT8A976B. By adding an external resistor conveniently, the oscillator will be constructed. The oscillator frequency can be adjusted by the external resistor. Pressing the ON/OFF button can control the output level of the PC pin. PT8A976, the auto-power-off function is achieved by an internal...
